fiClaims. (Cl.189-78) The invention relates to window sash constructions in which the rails of the sash are formed of extruded metal bars.

It is the object of the invention to obtain a construction in which said extruded bars have a portion for forming sealing engagement with the window frame, also, a portion forming a seat for the glass and provision for engagement of glass retaining means. Thus, all of the rails of the sash may be formed by bar sections of suitable length having mitered ends for engagement with each other at the several corners.

The invention consists in the construction of the said bars and in cooperating means for sealing and retaining the glass as more fully hereinafter described.

In the accompanying drawings:

Fig. 1 is a sectional perspective view of the sash;

Fig. 2 is a cross-section of the bottom rail;

Fig. 3 is a similar cross-section showing a modified construction;

Fig. 4 is an elevation of a portion of the rear side of the frame showing the glass securing means.

As above stated, the sides or rails of the sash are formed from extruded metal bars A, all being of the same general cross-section, including a plurality of web sections connected to each other at one end only. This permits of forming a hollow bar and at the same time permanently supporting the core members of the dies forming the extrusion apertures. As specifically shown in Fig. 1, the bar includes a front web portion A which may be fashioned to any desired ornamental form, a web portion A extending at substantially right angles from the outer edge of A, and a web portion A spaced from and substantially parallel to the portion A and extending from the portion A spaced from its inner edge. Bars of such cross-section form all of the rails of the sash, being bevelled at their opposite ends and united to each other, preferably by welding, to form a rectangular frame. In this frame the portions A are on the outer side and fit within the stationary window frame, the inner portion of the web A overlaps the outer face of the glass B, and the web A overlaps the edge of the glass. The glass is retained by resilient bars C of generally V-shaped cross-section which extend. the length of each rail along the inner face of the glass, being bevelled at their ends for juncture with the corresponding bars of adjacent rails. For holding the retaining bars C, the bars A are provided with a grooved portion A which is spaced from the inner edge of the portion A to form a groove or channel therebetween but is in rigid relation to such portion. This may be accomplished, as shown in Fig. 1, by forming the portion A at the end of a web portion A extending from the Web A generally parallel to the web A. An alternative construction is shown in Fig. 3 in which the portion A is connected to the portion A by a channel portion A all of said portions being integral. If the sash is mounted for swinging in the window frame the extruded bar forming the top sash rail has integral therewith a flange D of spiral 'cross seetion and the adjacent "extruded bar E of the frame has "an integral complementary spiral E for telescopicengag'emefit With-the spiral D to form a weather- 'ad hinge- I ,Tofmou'nt the glass in the sash a resilient strip F of suitable material, such as Vinyl plastic, is formed of a. cross-section "to fit ainst the portion of the front A .which overlaps the "glass and also extends between the edge of the glassand the portion A The bars Care than applie l by engaging the free edge of one leg C "of the V'with the grooved portion A of tlresa'sh. The 'bar'is then turned to bring the opposite leg C in contact with the outer face of the glass at a point near the apex of the V, said leg C extending inward through the slot A between the portions A and A of the bar through the slot and beneath the portion A to interlock therewith. As a result the bar C is held against the glass by resilient pressure. All of the bars C for the four sides of the sash are applied in this manner to hold the glass in position and also to form a finish for the inner face of the sash.

To adapt the structure for windows having a plurality of spaced panes, the portion A is elongated sufficiently to receive the same, and a second resilient strip F, similar to F, is used for spacing the panes. The retaining bars will contact only with the inner of the two panes, as shown in Fig. 3.

The construction of window frame forms no part of the instant invention but, as shown in Fig. 1, has a bottom bar G against which the sash seats and a top bar E having the complementary hinge member B.

What I claim as my invention is:

1. A window sash formed of extruded hollow metal bars mitered at opposite ends and united to each other to form the rails of a rectangular frame, each bar having a web portion overlapping the margin of the front face of the glass, a web portion at right angles thereto extending inward adjacent to the edge of the glass, and a portion spaced from the inner end of the latter portion to form an undercut slot therebetween with a groove in said spaced portion, the glass, and glass retaining means comprising a resilient strip of generally V-shaped crosssection extending along the rear face of said margin of the glass with one leg of the V engaging said groove, and the other leg near the apex of the V bearing against the glass and having an end portion passing through the space between said spaced portions and hooking under said web portion adjacent to the edge of the glass to hold said strip in glass retaining position.

2. The construction as in claim 1 in which said glass retaining strip extends the length of the sash bar with which it is engaged and is mitered at its opposite ends to adjoin similar strips for adjacent bars of the sash.

3. The construction as in claim 2 in which each sash rail has a web portion forming its rear side with which said groove portion is integral.

4. The construction as in claim 3 in which said rear side web portion together with said retaining strip for each rail form the rear finish of the sash.

5. In a window a sash rail having a flange overlapping the margin of the glass and a right angle portion adjacent the edge of the glass and extending beyond the same with an undercut slot therein adjacent and parallel to said glass and a groove in the portion in rear of said slot and glass retaining means comprising a resilient strip of generally V-shaped cross-section extending along the margin of the glass between the same and said right angle portion and across the slot therein also having a hook portion pressed into said slot to engage the hook thereof with the shoulder of said undercut portion and tensioned thereby to press at three points of the cross-section; one

This leg C is formed with a hooked portion C which passes by the springing.

against the glass another against said right angle portion beyond the slot and a third upward against said shoulder.

6. In a window sash, a rail having a flange overlapping the margin of the glass, a right angle portion extending inward adjacent to the edge of the glass with an undercut slot therein in rear of the glass and parallel to the edge thereof, and a longitudinally extending groove in the portion in rear of said slot; and glass retaining means comprising a resilient strip of V-shaped cross section extending along said rail, one leg of the V having the edge thereof engaging said groove and extending therefrom obliquely to and towards the plane of the glass, the other leg of the V adjacent to the apex thereof contacting the glass and extending therefrom into said slot with a latch hook thereon for engaging the shoulder of said undercut slot, whereby said strip may be pressed towards the glass until said hook is engaged, being thereby resiliently tensioned to press the apex portion against the glass.
